To address the stringent requirements of automobile manufacturing regarding the strength of body welds, the matching accuracy of interior parts, and the consistency of powertrain assembly, Wenzhou Yihe Intelligent Technology Co., Ltd. has launched a vision inspection system covering four major processes: stamping, welding, painting, and final assembly. This system employs laser penetration depth detection technology to monitor the quality of body-in-white welds in real time, achieving a weld width and penetration depth deviation recognition accuracy of ±0.1mm. Combined with a multi-view camera array, it dynamically measures body gaps and flatness, controlling the matching accuracy within ±0.2mm, helping automakers such as FAW-Volkswagen pass VDA 6.1 quality certification. In the powertrain field, the independently developed gear meshing detection system, combined with 3D point cloud modeling, performs micron-level analysis of transmission gear meshing clearances and tooth surface conta
